20090201923 | APPARATUS AND METHOD FOR A FAULT-TOLERANT SCALABLE SWITCH FABRIC WITH QUALITY-OF-SERVICE (QOS) SUPPORT - Embodiments of the present invention relate to portions of a switch fabric having a single logical stage and at least one physical stage. In addition, the data paths and the control paths of the switch fabric can be decoupled thereby allowing additional processing to be performed than would otherwise be the case with control rates that matched the high data rates. In other words, data cells received on high speed links can be spread over many lower speed links; consequently, the data cells can transit the switch fabric at that high speed while the control information associated with the data can be processed at that lower speed. Because the control information can be processed at a lower speed (associated with the control path), the control information can be processed over a greater period of time. | 08-13-2009 |

The barbs are spaced as close together as possible to prevent any axial movement of the bloodline connector when the assurance device is engaged about the mated connectors. | 08-19-2010 |
20120209168 | PERITONEAL DIALYSIS PATIENT CONNECTION SYSTEM - Peritoneal dialysis connectors, connector sets, connector systems and methods are disclosed. In an embodiment, a connector includes, a body, a spike located at a first end of the body, a sealing ring sized to seal inside a female connector and located adjacent to the spike end, threads located adjacent to the sealing ring, and at least one barbed ring located adjacent to the threads at a second end of the body. The at least one barbed ring is configured to seal the second end of the body to a tube. | 08-16-2012 |
20140094775 | CATHETER/FISTULA NEEDLE TO BLOODLINE CONNECTION ASSURANCE DEVICE - In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. One embodiment includes internal and external clamshells. Internal clamshell halves pressure seal to the bloodline connector, and form outwardly extending barbs. The external clamshell opens rotatably about at least one hinge and includes inwardly facing threads that catch the outer barbs of the internal clamshell. After a user connects the catheter or fistula needle to the bloodline, the user closes the internal clamshell about the bloodline connector. Then, the user closes the external clamshell about the internal clamshell, causing the inwardly facing barbs of the external clamshell to engage the outwardly facing barbs of the internal clamshell. Such engagement prevents axial movement of the bloodline connector relative to the external clamshell. | 04-03-2014 |
20140100547 | CATHETER/FISTULA NEEDLE TO BLOODLINE CONNECTION ASSURANCE DEVICE - In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. In one embodiment, the assurance device includes a clamshell having two halves that open rotatably about at least one hinge. The assurance device includes a male luer portion that pressure seals to the male luer portion of the bloodline connector. The bloodline male luer portion of the device extends to a female luer portion, which is lined with a compressible material that conforms around any industrial catheter/fistula needle connector when the assurance device is closed about the mated connectors. Once the assurance device is closed, this prevents axial movement of the bloodline connector relative to the assurance device. | 04-10-2014 |
20140100548 | CATHETER/FISTULA NEEDLE TO BLOODLINE CONNECTION ASSURANCE DEVICE - In general, multiple embodiments of a catheter/fistula needle to bloodline connection assurance device, which secures and strengthens a connection between an extension tube end of a catheter or fistula needle and a bloodline, are provided. A first embodiment of the assurance device is configured for use with a bloodline connector having locking clips which are biased slightly outwardly from the bloodline connector. The first embodiment of the assurance device includes clamshell halves that open rotatably about at least one hinge. The first embodiment of the assurance device includes an upper, threaded portion and a lower housing portion. The interior wall of the upper portion defines a plurality of barbs configured to engage with distal or moveable ends of the locking clips. Each locking clip is biased slightly outwardly to enable the distal or moveable end of the locking clip to fit between two respective barbs. | 04-10-2014 |
